SPECIFICATION forming part of Letters Patent'No; 529,631, dated .November 20, 1894.

Application filed June 16.1894.

To a/ZZ whom it may concern:

Be it known that I, JOHN SHERRY, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Torches; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

My improvement relates to that class of lighting and heating devices in which lthe liquid is forced `by atmospheric pressure upward to a burner where it is vaporized and the gas discharged in a jet which serves to produce the vaporizing action.

The invention consists in the special construction of the burner as hereinafter described and embodied in the claim.

In thedrawings-Figure 1- is a side elevation, partially in section, of the apparatus. Fig. 2 is an enlarged longitudinal section of the burner. Fig. 3 is a cross section of Fig. 2 in line x.

AAt indicates the tank, which may be o'f any suitable form and provided with a handle ct by which it is carried.

B is a pipe extending. down nearly to the bottom of tnetank, asin others of this class of apparatus, being also provided with a cut olf b by which the passageof the fluidis regulated.

O is a pipe through which air is forced bya pump or otherwise to the interior of the -tank over the oil to produce the necessary pressure to raise the latter to the burner. The tube is providedwith a cut-off c by which a charge of air can be retained.

The burner is attached to the top of 'the pipe Bl and stands horizontally as shown. It consists ofl two cylindrical tubes D and E, tted one within the other, leaving a thin annular jacket `space ol between them. This jacket space is closed at both ends, which is effected by fitting a shoulder f on the exterior of the inner tube closely within the outer tube j. at one end, bringing a second and largershoulder f of the inner tube against said end of the outer tube, and uniting the ends of the two tubes at the opposite end by a screw thread g. By this construction the two tubes.

end, and thence is discharged through a nipple K, which is so directed, centrally, as to blow the gas through the interior passage of the inner tube, which is open at both ends. The darne is ejected at the outer end of the tubes as shown in Fig. 1.

H is a shield, such asis ordinarily employed in this class of apparatus.

I is a hood, closed on the sides and outer end, the inner end being open and of proper shape to slide forward and back on the ends of the larger shoulder f', outer tube D, and conduit h. It incloses the gas pipe and nipple and forms, in fact, an extension ot' the outertube. Initssidesaremadelongitudinal slots m m, which form the vent openings to admit the outside air. By adjusting the hood endwise on the tubes more or less of the length of the slotsis cut' off, thereby grading the admission of air and consequently regulating the dame. The gas being blown through the tubes D E from end to end creates great heat inside the tubes, in addition to the blaze outside, and this intense heat vaporzes the oil, which is carried up and spread through the thin annular space d between the tubes. A very great radiating surface is obtained by the simplest construction. Therefore all the oil which enters the space is at once converted into gas, which, in turn, serves as the com` bustible agent to produce the heat. This construction is such that the parts are readily cleaned of the soot and sediment produced by the burning of oil between the tubes. The hood I is first removed, the pipe G turned to one side, and then the tubes are separated by unscrewing them and removing the inner one endwise, and the whole surface of both tubes can then be brushed or wiped free of dirt Without trouble. Much dilieulty has been experienced in cleaning burners of the ordinary kind, owing to their intricate passages.V

Having described my invention, what I claim as nevv,and desire to secure by Letters Patent, is-

In a vapor burner, the combination with a horizontal outer tube having one end reduced and interiorly screw-threaded, an oil supply pipe opening through the bottom of said tube near its center, and a conduitformed upon the ltop of said tube and extending from one end thereof to the center where it opens into said tube; of a second tube removably inserted within said outer tube and engaging the threads at one end, the exterior diameter of said inner tube being smaller than the interior diameter of the outer tube so as to form an annular space between the tubes, a shoul- -through the inner tube, and a hood inclosng the pipe and nozzle and shaped so as to fit close around and slide longitudinally over the inlet end of the outer tube and conduit, said hood having air inlets at its inner end, as and for the purpose set forth.

In Witness whereof I have hereunto signed my name Vin the presence ot' two subscribing Witnesses.
